Series of 5 Earthquakes Rock Alberta Within 4 Hours of Each Other

The Canadian Province of Alberta was rocked by a series of earthquakes on Tuesday - one's magnitude was roughly a 5.7 and another a 4.9, although reports vary. This is standard in the aftermath of seismic events, as seismologists gather their data.


Each aftershock measured over a 4.0 as well, making this one of the largest series of quakes in Canadian history.
